Tower Migration: cpu_fan error

I am moving my hardware to a new tower. Machine is not booting up because of the cpu fan error.

I can see all the fans are physically on on the machine.

I can see on the motherboard that the fans are not moving. This means the hardware of the tower is not communicating with the mobo/Asus software. Thing is I have the tower fan device connected to (b)cpu_opt right now as per the manual. I had the tower fan device plugged into (a)cpu_fan. I moved cable back to (a)cpu_fan. No dice gives a2 error on my mobo.

I believe all hardware components are set up correctly.

Error says press F1 to enter bios so I do. Fans are not spinning on the bios screen. They usually do. So maybe I have to turn something on...

There is a QFan Control so I press it. Next screen only shows options to change speeds of fans. Useless for this scenario.

So it has to be the cable on the tower fan device. Not making sense.

I see CE error on my mobo

I tried another connection on mobo (d)cha_fan2 no dice. I don’t think the asus bios software likes this cable connected.

Thoughts?

Solution 1:

Got it! i had to remove the cpu fan cables from the fan chassis on the side of the tower to the cpu fans on the mobo.
